▸Example Branch call (the "before")
import BranchSDK
Branch.getInstance().initSession(launchOptions: launchOptions) { params, error in
// Branch fingerprint + IDFA matching happens here.
if let referringLink = params?["~referring_link"] as? String {
// Route the user based on the deep link...
}
}
Branch.getInstance().userCompletedAction("Paywall Purchase", withState: [
BranchStandardEventTransactionId: orderId,
"revenue": price,
])Most analytics SDKs accept dozens of custom parameters per event. Respectlytics's API stores exactly five fields per event: event_name, session_id (rotated every two hours), timestamp, platform, and country. Extra fields are rejected with a 400. The discipline is structural — engineers can't accidentally add PII over time because the API refuses it.
☑Remove Branch cleanly
-
1
Remove Branch from your build (
Branch/io.branch.sdk.android:library/react-native-branch/flutter_branch_sdk) -
2
Remove
Branch.getInstance().initSession(...)anduserCompletedAction(...)call sites -
3
Decide what replaces Branch's deep-link routing — Universal Links + App Links are first-party alternatives (no SDK; OS-handled)
-
4
Remove Branch URL schemes from your
Info.plistandAndroidManifest.xml -
5
Delete the Branch app dashboard entry once events stop flowing
⇋Branch vs Respectlytics — 5-field event schema
| Branch | Respectlytics | |
|---|---|---|
| Stored fields per event | — see tool note above (typically dozens of params) | Exactly 5 |
| API enforcement of schema | Lenient (extras stored) | Strict (extras rejected with 400) |
| Per-user state computable | Yes (people profiles, user properties) | No (use account system) |
| Custom event properties accepted | 25–250 depending on tool | 0 |
❓Frequently asked questions
How do we segment events without custom properties?
By using distinct event names. Instead of track('purchase', { product: 'gold_pack' }), fire track('purchase_gold_pack'). The aggregation buckets event names automatically; no manual configuration. Keep your taxonomy short (under ~50 distinct names per matrix axis) to stay navigable.
We need per-event price for revenue reporting — how does that work?
It doesn't — and that's the point. Authoritative revenue lives in your billing system (Stripe, RevenueCat, App Store Connect) with refund-aware totals and currency-conversion handling. Mirroring revenue into product analytics produces two truths that drift over time.
What if we genuinely need a sixth field for legitimate reasons?
Three options: (a) encode the variant into the event name (e.g., paywall_purchase_pro vs paywall_purchase_basic); (b) keep per-user state in your account system and don't mirror it; (c) use a different tool for the specific use case. Most product teams find (a) or (b) sufficient.
How does the API actually enforce this?
JSON validation at the API gateway. A POST /api/v1/events/ with any field outside the 5 allowed keys returns HTTP 400 Bad Request with a body listing the rejected field names. Your integration test catches the regression on the first commit that adds an extra field.
